Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements At December 31, 2016 and March 31, 2016, the carrying amounts of cash, certain cash equivalents, restricted cash, marketable securities, receivables, drafts and accounts payable, short-term borrowings and other current liabilities approximated their estimated fair values because of the short maturity of these financial instruments. The fair value of our commercial paper was determined using quoted prices in active markets for identical liabilities, which are considered to be Level 1 inputs. Our long-term debt is carried at amortized cost. The carrying amounts and estimated fair values of these liabilities were $7.7 billion and $8.0 billion at December 31, 2016 and $8.1 billion and $8.6 billion at March 31, 2016. The estimated fair value of our long-term debt was determined using quoted market prices in a less active market and other observable inputs from available market information, which are considered to be Level 2 inputs, and may not be representative of actual values that could have been realized or that will be realized in the future. Assets Measured at Fair Value on a Recurring Basis Included in cash and cash equivalents at December 31, 2016 and March 31, 2016 were investments in money market funds of $0.6 billion and $2.4 billion, which are reported at fair value. The fair value of the money market funds was determined by using quoted prices for identical investments in active markets, which are considered to be Level 1 inputs under the fair value measurements and disclosure guidance. The carrying value of all other cash equivalents approximates their fair value due to their relatively short-term nature. Fair values of our forward foreign currency derivatives were determined using quoted market prices of similar instruments in an active market and other observable inputs from available market information. Fair values of our foreign currency swaps were determined using the quoted foreign currency exchange rates and other observable inputs from available market information. These inputs are considered Level 2 under the fair value measurements and disclosure guidance, and may not be representative of actual values that could have been realized or that will be realized in the future. Refer to Financial Note 14, "Hedging Activities," for more information on our forward foreign currency derivatives including foreign currency forward contracts and swaps. There were no transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy during the third quarters and first nine months of 2017 and 2016. Assets Measured at Fair Value on a Nonrecurring Basis We measure certain long-lived assets at fair value on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. If the cost of an investment exceeds its fair value, we evaluate, among other factors, our intent to hold the investment, general market conditions, the duration and extent to which the fair value is less than cost and the financial outlook for the industry and location. An impairment charge is recorded when the cost of the asset exceeds its fair value and this condition is determined to be other-than-temporary. At December 31, 2016, assets measured at fair value on a nonrecurring basis consisted of goodwill for a reporting unit within our Technology Solutions segment, as further discussed below. There were no liabilities measured at fair value on a nonrecurring basis at December 31, 2016. There were no assets or liabilities measured at fair value on a nonrecurring basis at March 31, 2016. Goodwill As discussed in Financial Note 3, "Goodwill Impairment," during the first nine months of 2017, we recorded a non-cash pre-tax charge of $290 million ($282 million after-tax) to impair the carrying value of goodwill related to our EIS business, which is a reporting unit within our Technology Solutions segment. The impairment primarily resulted from a decline in estimated cash flows. The goodwill impairment test requires us to compare the fair value of the reporting unit to the fair value of the reporting unit's net assets, excluding goodwill but including any unrecognized intangible assets, to determine the implied fair value of goodwill. If the carrying value of goodwill for the reporting unit exceeds the implied fair value of goodwill, an impairment charge is recorded for that excess. Fair value assessment of the reporting unit and the reporting unit's net assets are considered a Level 3 measurement due to the significance of unobservable inputs developed using company specific information. We considered the market approach as well as income approach using a discount cash flow (“DCF”) model to determine the fair value of the reporting unit. The DCF method was used to determine the fair value of intangible assets.
